Welcome Raysp30.If you can tell us where you're at,mpg wise,and your target mpg,that will give us a "performance envelope" to think about.Unfortunately for you,the notchback style body is the least efficient aerodynamically,however has great utility.36-percent of your future potential mpg is locked up in the air behind the Saturn.Without some changes to the back of the car,that savings will be beyond your reach.
